Opis:
This paper presents a review of most important zoonotic diseases that are threatening human world population in the first 20 years of XXI century. Zoonoses diseases naturally transmitted through several modes from vertebrate animal hosts to humans. SARS-CoV-2 - severe acute respiratory syndrome coronavirus 2, was identified as the cause of an outbreak of COVID-2 pandemic in humans in 2019/2020. Coronavirus positive Chinese bats and an unrecognized yet natural reservoir of emerging SARS-2, are indicated as a primary source of infection. So far, there is no evidence that companion or farm animals can become infected by contact with a sick/infected person, so SARS-2 virus strains isolated from humans are not zoonotic. This review contains a description of SARS-2 virus structure, genetic diversity, structure and function of viral proteins, including class I viral fusion protein S. The review also includes an assessment of epidemiology of SARS-2 infection, criteria and epidemiological interactions, perspectives on emerging zoonotic disease research in contact with public health service. More closed cooperation between different services, including Veterinary Services, with WHO and OIE international standards, as e.g. One Health partnership, is essential to avoid or minimize risk of new infections in future.

Opis:
This paper presents a description of the methodology developed for estimation of pathogen transmission in transport and the results of the case study application for long-distance passenger transport. The primary objective is to report the method developed and the application for case studies in various passenger transport services. The most important findings and achievements of the presented study are the original universal methodology to estimate the probability of pathogen transmission with full mathematical disclosure and an open process formula, to make it possible to take other specific mechanisms of virus transmission when providing transport services. The results presented conducted an analysis on the mechanisms of transmission of SARS-CoV-2 virus pathogens during the transport process, to examine the chain of events as a result of which passengers may be infected. The author proposed a new method to estimate the probability of transmission of viral pathogens using the probability theory of the sum of elementary events. This is a new approach in this area, the advantage of which is a fully explicit mathematical formula that allows the method to be applied to various cases. The findings of this study can facilitate the management of epidemic risk in passenger transport operators and government administration. It should be clearly emphasised that the developed method and estimated values are the probabilities of pathogen transmission. Estimating the probability of transmission of the SARS-CoV-2 virus pathogen is not the same as the probability of viral infection, and more so the probability of contracting COVID-19. Viral infection strongly depends on viral mechanisms, exposure doses, and contact frequency. The probability of contracting COVID-19 and its complications depends on the individual characteristics of the immune system, even with confirmed viral infection. However, it is undoubtedly that the probability of transmission of the SARS-CoV-2 virus pathogen is the most reliable measure of infection risk, which can be estimated according to the objective determinants of pathogen transmission.
